Version:           0.0.1 (using KDE 4.5.3)

When I click on a magnet link I receive the following error message:

"The requested operation could not be completed
Cannot Initiate the magnet Protocol

Still the case with KDE 4.8.3 (Gentoo sources).

Can either one of you provide a link to test this against ? The magnet kio comes with ktorrent so if it does not work, then it needs to be reported against ktorrent not konqueror.

In konqueror 4.8.4 this works fine.  I had trouble with this in older versions of KDE, at least the built in browser of ktorrent's seearch plugin resulted in the same error message.

It could of course be caused by some weird character in the magnet uri which isn't properly passed to ktorrent when forking ktorrent. Maybe konqeror didn't shell quote the uri parameter for ktorrent ?

Comment 4 Darin McBride 2012-09-17 12:44:01 UTC

Aha.  I'm on KDE 4.9.1, though I've had this problem with 4.8 and probably 4.7, maybe even earlier.

However, if I switch the view mode from WebKit to KHTML, then magnet links work.  I hadn't thought to try that any earlier.  Maybe this is a problem with WebKit, then.  Maybe m.wege can confirm whether s/he is also using WebKit?

Comment 5 Joris Guisson 2012-09-17 13:02:23 UTC

Note that the built in browser of ktorrent's search plugin  also uses webkit

So it looks like a webkit issue.

Then this should be reported upstream, webkit is an external dependency we have no inlfuenc over.

Comment 7 Darin McBride 2012-09-18 18:50:06 UTC

https://bugs.webkit.org/show_bug.cgi?id=97004 suggests that KDE is using Webkit improperly.  Either that or someone has to provide a patch.  I'm not sure which.

Comment 8 Dawit Alemayehu 2012-09-19 04:05:53 UTC

Might not really be a webkit issue. We need to first investigate the KIO/QNetworkAccessManager bridge to make sure it is not doing anything that prevents magnet urls from working.
